Google Code begins hosting AJAX Libraries
Google are using their CDN to host a number of Javascript libraries (including jQuery, prototype, and others). This means that a browser should only have to download the code once, rather than once for each site they visit that uses it.
You can link directly to the .js files, or use a Google API call to always load the latest version of a library.
http://code.google.com/apis/ajaxlibs/Google Code: Google Contacts Data API
The Contacts Data API allows client applications to view and update a user's contacts. Contacts are stored in the user's Google Account; most Google services have access to the contact list.
Your client application can use the Contacts Data API to create new contacts, edit or delete existing contacts, and query for contacts that match particular criteria.
